The Disastrous Flight of Bumblebee 24

Actually, this bumblebee ‌barely got off the ground at all this year. It started off with a heartbreaking rig failure and ended with some horrendous local noise.

I had a late-breaking change of plans this week. I originally planned to operate in the Flight of the Bumblebees (FOBB) contest from a nearby POTA entity. Instead, I ended up in central Pennsylvania helping a family member recovering from a recent surgery.

So, I activated Plan B: take my new KH1 along and make a few contacts from the backyard. What could go wrong with that? A lot, as it turns out.

Using my homebrew ground mount, I set up a new antenna on my lightweight telescopic pole. The antenna comprises a 15-foot radiator and a 7.5-ft counterpoise fed through a 4:1 unun. (More about that antenna in another post.) I ran a 6-foot length of RG-316 coax over to the KH1. 

I easily got a 1:1 match on 20M and up, but it wouldn’t load up at all on 40M. Going back to 20M, I started operating. Something on the display didn’t look right. It turned out that I wasn’t getting any power output. When I pressed the ATU button, I heard some relay clicking, but there was no power or SWR displayed after tuning. When I keyed up, the display showed zero bars of power and one bar for SWR.

I checked to make sure I wasn’t in “Test” mode (I wasn’t). Next, I started pouring through the settings to make sure I hadn’t messed something up. Nothing looked out of the ordinary to me. I tried the built-in whip on 20M, but still no power out.

After spending an inordinate amount of time playing around with the KH1, I packed it up and brought out my Penntek TR-35. My trusty Elecraft T1 ATU also refused to load up on 40M.

So, 20M was the only band working for me, given the rig I was using. I could have set up a different antenna, but I didn’t have that much time. 

The 20M band had some horrendous local noise, so it was rough going. I worked one bumblebee in Missouri, and that was it. Frustrated with my inability to hear any other FOBB activity through the noise, I called it quits. I needed to get back inside to take care of a few things, anyway.

Having owned my KH1 for less than a week, you can imagine my disappointment. I shot off a message to the support folks at Elecraft, so hopefully, they can help get this issue resolved before I head down to North Carolina on vacation next month. (Fingers crossed)

I hope you all did better in the contest than me.
